Description

MOBILE COMMUNICATIONS NETWORK, METHOD AND APPARATUSES}

The present invention relates to a communication network for a mobile user, the communication network for a mobile user comprising a user subsystem and a transmission subsystem connected by an access subsystem, wherein the access subsystem comprises: Providing each of the subsystems with a user access communication interface and a transport / access interface (Iu) suitable for allowing the exchange of information flow (TS) between the subsystems, the access subsystem (AST) being a cellular telephone. Send a signal to the coverage area of the network.

Based on various analyzes, we can expect to see a significant increase in the amount of information exchanged between mobile wireless telephone terminals and the network of these service providers in the near future. Given these future demands, various national and international organizations (eg, ITU, ETSI, FCC, etc.) dealing with regulations affecting radio frequency allocation and usage and the relative standards of data processing and single modulation technology can be used by mobile networks and users. They agreed to set standards (or GSM GPRS and groups of standards such as IMT2000 or 3G) that would allow a significant increase in the exchange rate between mobile terminals. For example, the IMT2000 standard group includes improved data such as other networks of the same population (eg DECT) and previous generation (2G) wireless telephone networks (eg GSM and PCS) and GPRS, DEGE, etc. (commonly referred to as 2.5G). It includes CDMA 2000 and a new standard called Universal Mobile Telecommunication System (UMTS) or 3G (3rd generation) that allows transport version and protocol compatibility of video conferencing and Internet networks (eg IPv6). At the same time, new software and signal processing methods and standards reduce bandwidth requirements for digital broadcasting of video clips, TV programs, and audio programs, and digital networks such as the Internet, intranets, and the like, and wireless local area networks. In addition, there has been a continual evolution to allow the transmission of video, music and video over wireless cellular networks. In addition, all the technologies necessary to produce low cost, efficient and high performance wireless mobile terminals are constantly developing. These technologies include basic phone functions, various additional complex functions (graphical display with satisfactory resolution, typical functions of a PC, the ability to interpret and refine various standards and protocols of the Internet field, massive data storage and serial interface Operation, synthesis and playback of audio and video files in accordance with various standards, operation of serial interfaces by modems, infrared and wireless interfaces for data exchange over short distances with other digital devices or network gateways, reception and processing of GPS signals, It contributes to the production of mobile radio terminals that can incorporate complex interactive game play, rapid encryption of files, speech recognition and synthesis, etc.).

The dissemination of new terminals, which can then provide efficient internet access, show video, graphics and play voice, music and television file-data, and also download from the Internet, is possible in terrestrial wireless networks for mobile phones. It seems reasonable to assume that the result will be a significant increase in the amount of transmitted data.

Therefore, in addition to implementing improved standards, in order to provide quality services to consumers, wireless network providers continue to invest in upgrading their network capacity to meet increasing data traffic demands. You will have to increase it.

A good example is the third generation (3G) of cellular networks based on the UMTS standard designed for multimedia communications. With such a system, personal communications can be improved by access to high-definition video and / or video and information or services on public and private networks, and by utilizing the highest data rates and the highest communication flexibility available for each system. Can be.

This system has the following features among others:

Varying bit rates to provide a wider bandwidth suitable for the required service (from approximately 16 Kbps for voice communication to approximately 384 Kbps, and up to 2 Mbps for “high speed multimedia” service);

Multiple transmission services for different quality requirements with a single connection;

Quality requirements from 10% frame error to ^10-6 -bit error rate;

Compatibility with second generation and 2.5G systems (ie GSM handover intersystems for better coverage and traffic balance)

Support for asymmetric traffic for uplink (from user to provider) and downlink (from provider to user)

High efficiency in spectrum use

Compatibility of Frequency Division Duplex (FDD) and Time Division Duplex (TDD) connection modes.

The most important characteristics of a network based on the UMTS standard are the high user bit rate, compatibility with Internet standards, the ability to run multimedia files and the "always on" connection mode for the terminal.

Initial use of UMTS networks will consist primarily of voice and Internet content, but it is logical to predict that multimedia data traffic will increase later. Since the requested information will be primarily available on the Internet, it is important to implement efficient management of TCP / UDP / IP traffic in the UMTS network.

At the level of the network structure, the UMTS network consists of a combination of logical network elements, each with special functions. In the standard, both logical elements and open interfaces between them are also defined to enable automatic identification of the physical elements of the network.

The existence of an open interface allows interconnection to UMTS networks as well as modes not explicitly envisioned by the current standard, particularly in access networks called UTRAN (UMTS Terrestrial Radio Access Network) in the 3G standard. Regarding the detailed description of services and performance that are standardized or in the process of definition for mobile telephony networks 2.5G and 3G, in the accompanying Figure 1 described below, some of the elements of the UMTS network required to describe the invention are described. Although shown, system designers 3GPP and 3GPP2 (Third Generation Partnership Project and See product documentation for Third Generation Partnership Project 2).

1 shows a block diagram of a top-level structure of a popular form of a communications network (UNET) for mobile users in accordance with the UMTS standard including three subsystems connected to each other:

User terminal subsystem (STU) is referred to as User Equipment in the standard. This user terminal subsystem (STU) constitutes a user terminal system, i.e., a mobile terminal such as a cellular phone. The user terminal subsystem (STU) is connected with a communication network (UNET) for mobile users, in particular with an access subsystem (STA) via an access / user interface (Uu) in which an information flow (TS) is received and transmitted. do. As mentioned, this access / user interface (Uu) is open to allow operation in conjunction with multiple terminal brands. The user terminal subsystem includes a mobile equipment (ME), which is a cellular phone handset that communicates by means of a specially designed equipment interface (Cu) and a user ID module (USIM) similar to the SIM card of the so-called GSM standard.

Access Subsystem (STA): The Access Subsystem (STA) configures network access with the UTRAN system of the UMTS standard and is connected with the transport network (STT) via the transport / access interface (Iu).

Transport Subsystem (STT): This transport subsystem, identified as the Core Network in the UMTS standard, constitutes the transport network of the UMTS system. These transport subsystems, in addition to being connected to the access subsystem STA by the transport / access interface Iu, are all other existing networks (external networks, PSTNs, ISDNs, Bs) identified by the EXTNET block in FIG. Must be able to connect to the Internet (ISDN, Internet, etc.). The transport subsystem (STT) includes a mobile services switching center (MSC), a home location register (HLR), a database visitor location register (VLR), an interconnect node or a gateway. Information management, routing, and switching typical of a wireless telephony network including a gateway mobile switching center (GMSC) and a node for running a Serving GPRS Support Node (SGSN) or Gateway GPRS Serving / Support Node (GGSN). Means for include.

In FIG. 1, an access sub-station corresponds to a base station (SNB) corresponding to a base station defined as Node B in the UMTS standard, such as a wireless station broadcasting to an area identifying a cell or system domain of a mobile phone. It can be seen inside the system STA. Their main function is to exchange information flows (TS) through the user terminal subsystem (STU) and access / user interface (Uu). Such a base station (SNB) performs management of major radio resources such as, for example, power.

Inside the access subsystem STA is included, among others, a network radio controller (CRR) (referred to as the Radio Network Controller (RNC) in the UMTS standard). This radio network controller (CRR), including all base stations (SNBs) connected to the CRR by a dedicated controller-station interface (Iub), has full control over all radio resources in that area.

The wireless network controller (CRR) manages one or more base stations (SNBs), communicating with the transmission subsystem (STT), in particular the switching center (MSC), setting up wireless channels (setup and disclosure of connections), frequency hopping. Manage internal handovers and other functions. In large urban areas there are a large number of base stations (SNB) controlled by only a few wireless network controllers (CRRs).

Because of the foreseeable increase required for the exchange of multimedia information, the network (UNET) shown in FIG. 1 will have to move the increasing traffic, which is the transport / access interface (Iu) and access / user interface (Uu) from the external network (EXTNET). Must be sent in both directions. As mentioned above, in order to provide a service that is qualitatively satisfactory to the customer, the manager of the UMTS network and the wireless network must make continuous investment to meet the increasing demand of the network performance. In addition, the demand for new services will require additional resources to provide for the planning, execution, and management of these new services, which in turn increases the cost and time of execution even further.

The present invention addresses the shortcomings and shortcomings enumerated above and is intended to provide an improved and more efficient communication network for mobile users.

In this context, a primary object of the present invention is to propose a communication network for a mobile user that allows a user to receive data with high transmission capability.

Another object of the present invention is to propose a communication network for a mobile user, which enables simple and economical implementation of a new type of service.

It is a final object of the present invention to provide a communication network for mobile users that is compatible with current and new cell phone standards (eg IMT2000) and in particular the UMTS standard.

To achieve this object, it is an object of the present invention to provide a communication network and / or base station and / or wireless network controller for a mobile user and / or information transmission method / means comprising the features of the appended claims.

Further objects, features and advantages of the present invention will become apparent from the following detailed description and the accompanying drawings, which are provided by way of non-limiting example.

The communication network for a mobile user according to the present invention provides an integrated structure that can carry a vast amount of multimedia data flow directly through a satellite to a base station connected to the user's terminal, thus avoiding traffic saturation in the terrestrial transmission network. Allow for increased data transfer capability. Thus, the traffic saturation is out of the terrestrial transmission network.

The present invention is that most of the new multimedia traffic is asymmetric in the sense that most of the data flow will move from the network to the user, and most of these needs for data are compatible with broadcast and multicast transmissions, The latter is based on the observation that it is personalized in both directions by the customer and the network administrator as a function of the typical cycle of events, interests, demands, and client activity. In this regard, it is contemplated that the network architecture will be greatly increased in capacity to conform to the new standard, making it the most economical and fastest in implementation.

Therefore, it seems desirable to integrate the planned terrestrial wireless network with all components of other networks already existing, characterized by high levels of reliability, high transmission capacity, moderate access costs, and the very low cost interface devices required. . Integrating with 2.5G or 3G wireless networks is a cost-effective means of delivering digital (or analog) TVs, audio channels, and Internet content channels or data streams and programs specifically for mobile users, in order to economically transfer most of the future new multimedia traffic. The broadcast-only geostationary satellite would be the most viable and suitable.

In addition, information services, on a global, national or regional scale, simultaneously with the above-described connection with satellites, are analogue modulation and in the near future digital formats (e.g. DVB-T, DAB-T iDAB, DRM or similar standards or derivatives thereof). Functional integration with terrestrial TV or audio wireless broadcasting may be economical in operation.

Therefore, the idea of the present invention is to integrate and add the access network in the access network of the UMTS system (UTRAN) of the communication network for mobile users, i. Where possible, it also integrates with broadcasts from terrestrial stations.

This integration allows the use of geostationary satellites that require typical directional antennas (not suitable for providing mobile services) to provide mobile services. This result is, for example, connected to satellite transmission content and decode / encode the content transmitted from the satellite using a parabola antenna, eg a fixed directional parabola antenna, installed at each base station (SNB) or each network radio controller (CRR). It is obtained by supplying through the unit to enable access to the radio resources of UMTS operated by the base station (SNB). This allows a user of a communication network (UNET) to use a service that requires a fixed connection in another way without significantly increasing the traffic on the transport subsystem (STT).

In Figure 2, a block diagram shows a base station according to the present invention. The base station SNB implements a station controller interface Iub as shown in FIG. 1 to the base station SNB, and also has a satellite interconnection device having a satellite receiving means (RTS) for connecting with one or more stationary satellites. It is connected to (GSB). To this end, in FIG. 2, the geostationary satellite GS transmits the satellite channel BS in broadcast mode, which satellite channel is received by the satellite receiving means RTS and via the interface Iub the base station SNB. Is sent). The base station (SNB) then broadcasts the content of the satellite channel (BS) within the cell coverage area.

The satellite receiving means (RTS) is completely analog in terms of means for receiving domestic television programs, for example a low noise block amplifier / downconverter (LNB), a decoder with a satellite signal format and the expected service. It may include recorders in one or more standards that are compatible with the UMTS specification for the form. A conceptually equivalent solution is to route the SNB and analog broadcasting ground station to the final user terminal with another antenna and receiver-digitizer-encoding unit. (Audio, TV or dedicated full-band or sub-band program) or with another antenna-receiver-decoder-re-coder unit for a digital ground station (audio, TV or provided program or Sub-program).

Some of the possible services and data streams may be reserved for operators of emergency public protection, safety services or general / public utility services.

3 shows a network satellite interconnecting device (NGS) by satellite receiving means (NRTS) with a transmission / access interface (Iu) towards a wireless network controller (CRR). As such, the network satellite interconnection device (NGS) is connected to a wireless network controller (CRR). A network satellite interconnection device (NGS) located on the hierarchical network level of the transmission system (STT) can also operate all necessary communications with a database (HLR). The database (HLR), as known, contains all the information associated with the customer and each single user required to manage the customer's mobility. That is, the network management system constructs a database that continuously stores various data related to users provided through the database. For simpler services, it may not be necessary to communicate with network resources that control and manage the mobility of users. In other words, the Network Satellite Interconnect (NGS) can operate without having to know where the various users are located. In the case of a personalized service, information about the location of a particular user may be used instead of building the service. In such a case, it is important to communicate with the database (HLR). For the same hierarchical level reason, the network satellite interconnector can carry out all necessary communications with an Intelligent Network Node (IN). These nodes contain all the information related to each single user needed to manage complex communication services. Both the database (HLR) and the intelligent network node (IN) are network elements with open interfaces between standardized communication protocols.

A communication network (UNET) for a mobile user with a base station (SNB) and / or a wireless network controller (CRR) allows for the following applications:

-High quality internet navigation (web type).

Most efficiently personalized data streaming (e.g. email, multimedia mail, dedicated special data, etc.).

One or more broadcasting channels (standard TV or audio channels or mobile user specific content, data and video clips) are provided to all authorized mobile customers.

A single service center is sufficient for the entire network and only a minimal amount of communication data between the terminal and the service center is needed to manage this additional service.

For the quality of Internet services, it would be possible to use services based on updatable databases (eg, e-commerce, reservations, etc.). The quality of these services depends primarily on the number of access points available in the network that can be co-located with the SGSN. Many access points can be easily updated via satellite.

For access to satellite Internet service providers (ISPs) using the high downlink capacity provided by satellites, it is possible to extend their offerings to UMTS mobile customers (without any form of modification to the user terminal), It is also extensible to everyone who owns an authorized UMTS terminal for the service. With regard to personalized streaming, data streams (eg, a few megabytes (Mb)) with personalized content such as newspapers, stock market information, sports news or other subscription services are received at the user UMTS terminal, directly from the base station. Would be possible. For this reason, the network satellite interconnect device GSB or NGS may be provided with a storage capability in a manner that enables storage of BS flow data transmitted from the satellite GS. The satellite GS may transmit information content at regular intervals, such as news services that change slowly and gradually over time. In this manner, sending only satellite specific changes / updates required by the user will be possible by the request from the user terminal keyboard. For example, a news service includes domestic news stored in the memory of a network satellite interconnect device (GSB or NGS), whereas after a user's request for a news service, the satellite channel (BS) is a local news bulletin or a specific topic. I will send more explanation about it. In this way, the information content load can be reduced by the carrier on the satellite channel BS transmitted by the satellite GS.

For example, if a channel is reserved for a base station for this service performed by an additional satellite channel (BS), each cell can serve up to 10 customers per minute and a single service center is all that is needed for the entire network. This is achievable with very little data between the terminal and the service center.

The above description provides a clear idea of the features and advantages of the present invention.

The communication network for a mobile user according to the present invention provides an integrated structure that can carry a vast amount of multimedia data flow directly through a satellite to a base station connected to the user's terminal, thus avoiding traffic saturation in the terrestrial transmission network. Allow for increased data transfer capability. Thus, the traffic saturation is out of the terrestrial transmission network.

Another advantage is that with a single satellite radio radiation, base stations (ten thousands) belonging to one provider all start operating each time they are installed. Having a base station and / or antenna radio controller and associated devices for satellite reception is as if each mobile terminal could receive a multimedia program directly from a stationary satellite. The use of a geostationary system for broadcasting information indicates that the reception system (interface device, antenna, LNB, decoder, recorder for standards compatible with the UMTS environment) that the base station or controller (CRR) must have is simple and economical. In particular, it is useful.

Moreover, the rental of similar channels or satellite transponders or portions of transponders is particularly cost effective with regard to the development of special services for mobile phones. Furthermore, the communication network for a mobile user according to the present invention advantageously utilizes the area covered by the cellular network, i. E. The base station and the controller already part of its access system. Then, the aforementioned mobile communication network according to the present invention may be considered to be different from the network form integrating a mobile satellite network and a terrestrial network for a mobile user. Such networks tend to increase coverage of the service area that is not covered (because of low customer density), but do not significantly increase traffic in the transport network and instead allow an increase in the bit rate usefully achieved in accordance with the present invention.

The communication network for mobile users according to the invention allows the use of the planned service with maximum flexibility and easy execution in the shortest time. This makes it possible to achieve an advantage in the ratio of quality to cost of the services provided using broadcast or multicasting mode satellites. An added advantage is that it can be broadcast or multicasted directly. In addition, communication networks for mobile users using the present invention are compatible with UMTS and other similar standards of the CDMA2000 or 3G family. It is also compatible with future systems that use open interfaces or are based on structures similar to older, updated systems such as GPRS.

Moreover, the communication network for a mobile user according to the present invention allows a provider to strategically usefully optimize bandwidth in certain cases where the user cannot watch video (while driving, working, etc.) but the audio program can listen. do. Statistically, user behavior tends to be cyclical (eg, breakfast, driving to work, work, lunch, work, driving to work, personal behavior, etc.).

Given the continued miniaturization of massive memory and the rapid development of the workability of small microprocessors, it is possible to store movies, music, personalized video or audio news of various themes and to operate video, graphics and audio messages or text via e-mail. It is thought that it will be possible to produce a miniaturized terminal that can be used in a short time.

Moreover, multimedia service providers are also expected to move towards providing interactive TV as well as music and audio services with content and updates selected by the customer.

Compatible with the "always on" connection mode provided by the GPRS and UMTS systems, this approach allows the provider to switch to memory cache at various levels (at network radio controllers, base stations and user terminals). It will be beneficial to reduce the need for bandwidth at peak time in < RTI ID = 0.0 >

Without departing from the novel idea of the invention, many modifications to the mobile user and / or base station and / or wireless network controller and / or the method for sending the above-described information via examples are possible in the relevant industry for telecommunication networks. As will be apparent to one of ordinary skill in the art, in the practical practice of the present invention the components may often differ in form and size from those described and may also be substituted by technical equivalents.

For example, with a large number of base stations in an access network with the necessary devices to realize a two-way satellite connection, and installing a radio controller, a single user and a huge amount of two-way with a properly fixed, low-cost domestic satellite radio receiver When future use of large-bandwidth geostationary satellites to enable exchange of data flows is possible, users who can tolerate short response delays can conduct long-distance video conferencing or video transmissions without overloading the terrestrial network. Will be done. On the other hand, as a provider, it will also be possible to install a remote base station (in addition or temporarily) at a location lacking a communication infrastructure or at a location with insufficient or inadequate infrastructure.

The base station according to the present invention allows two-way communication between the satellite and the UMTS terminal; In Figures 2 and 3 only the downlink, i.e. the communication from the service provider to the user, is described, and this transmission direction is now more appropriate and provides significant economic benefits by providing high quality, innovative services for UMTS users in the near future. Can provide.

However, access to the UMTS interface allows the use of the access subsystem not only as an access network for the UMTS transport network, but also as the access infrastructure of the satellite network. The structure described above allows a user with the next generation of mobile terminals to directly access satellite broadcast services (normal TV, "CD quality" audio and Internet or personalized data) reserved to date for users with appropriate domestic satellite interfaces. To allow.

Since a typical base station can drive a limited number of channels at high speed, using only a small number (usually one or two) of non-interactive or partially interactive television channels seems cost effective. Some of the base stations can be installed on buildings. In general, since there are various common elements between the satellite connection system integrated in the base station and the domestic satellite connection system, the elements of the domestic satellite connection system can be quickly and economically implemented to perform the functions of the shared satellite connection system for the whole building. Organizing a base station with it may be cost effective. Once again focusing on the use of widely shared equipment in existing buildings, it will be possible to equip new base stations with existing satellite antennas in homes, apartments or office buildings.

Finally, it is clear that the communication network using the present invention is not limited to the structure required for UMTS. For example, when using a GPRS or DECT system, it can be used in connection with the 2.5 generation standard. The communication network according to the invention is also a Local Area Network (LAN), such as not based on Bluetooth, or Wireless Ethernet Compatibility Alliance (Weca) IEEE802.11 A or B, or even HomeRF or also Ethernet. There is an integrated application. Signals according to the protocol may be carried through a low mobility picocells access subsystem (eg, at a supermarket, airport) of a UMTS (or GPRS) network connected to a satellite antenna according to the invention. The subsystem according to the invention is different and local with respect to broadcasting by a general UMTS service for terminal users receiving at both UMTS and LAN frequencies, and can be additional with respect to general broadcasting via LAN and LAN servers. It is integrated into the aforementioned wireless access point (AP for Weca) to broadcast the information.
